Explanation:

On the Ravi River, the earliest project built was the Madhopur Headworks, in 1902. It is a run-of-the river project (no storage envisaged) to divert flows through the Upper Bari Doab Canal (also known as Central Bari Doab Canal) to provide irrigation in the command area of the then unified India. Doabas formed by the Ravi River are known as the Rechna Doab – between the Chenab and the Ravi River, and the Bari Doab or Majha – between the Ravi and the Beas River.Upper Bari doab takes its origin from Madhopur Headworks.
